An angle attachment of a hand-held power tool, such as a spiral cutting tool, includes an angle attachment housing having an open first end adapted to be attached to the motor housing of the power tool. An alignment bearing is mounted in the angle attachment housing and adapted to receive and support a first shaft having a first shaft gear mounted thereon. An attachment shaft is mounted in the angle attachment housing at an angle, e.g., a right angle, to the first shaft. The attachment shaft includes an attachment shaft gear mounted thereon which is engaged with the first shaft gear. One or more attachment shaft bearings are mounted in the angle attachment housing to support the attachment shaft for rotational movement thereof. The first shaft is coupled to a motor shaft of the power tool before the angle attachment housing is attached to the power tool motor housing. Rotation of the first shaft by the power tool motor causes rotation of attachments attached to the attachment shaft mounted at an angle to the first shaft by means of the gear mechanism formed by the engaged first shaft gear and attachment shaft gear.

Angle attachment for power tool

A guide () for setting the depth of cut of a rotary cutting tool, or other hand-held power tool, which automatically locks into a desired position to set the depth of a cut without requiring manual operation of a locking knob or similar structure. The depth guide is released from the locked position by actuation of a release switch (). The depth guide includes a depth guide base (), a depth guide shaft () attached to the depth guide base, and an automatic locking and release mechanism () coupled to the depth guide shaft. The automatic locking and release mechanism and depth guide shaft may be mounted in a handle () of the hand-held power tool, such as a detachable handle, for mounting the depth guide to the tool.
